"Historic Preservation Contractor"

Ornamental Plaster Restoration, Historic Preservation.
Our goal is to install new work with the least disruption to existing flat and ornamental historic plaster.


At Historic Structures, we have found an understanding of the design and construction techniques of period plaster ornament to be an essential for producing effective, integrated solutions for important historic home and building interiors. Such expertise enables us to furnish invisible alterations which produce the least loss of original historic ornamental plaster. Our services range from stabilizing original work to researching materials to the moldmaking and casting required for producing reproduction work.

Historic Structures is pleased to work with clients conserving, restoring or reproducing ornamental and flat plaster from the early eighteenth century to the early twentieth. Our experience and commitment can help to assure an efficient and satisfactory result for your project as it has for so many others. We are glad to hear about your significant ornamental plaster restoration or reproduction project:
